You've probably already forgotten that LinkedIn was hacked back in 2012, but you could still be affected by that four-year-old security breach. According to Motherboard, someone going by the name "Peace" is selling (if he hasn't sold them yet) 117 million LinkedIn username and password combos on a dark web marketplace for 5 Bitcoins or around $2,300. When the attack was first discovered, only 6.5 million users' details were leaked -- this dump reveals that the breach was much, much bigger. In fact, a hacked data search engine told Motherboard that the database Peace listed contains 167 million accounts. It's just that only 117 million have both usernames and passwords.
